IO-Link Device Phy with integrated frame handler

The CCE4502 is a highly integrated device-side IO-Link compliant transceiver IC. The built-in hardware based IO-Link frame handler provides full IO-Link protocol handling facilities making it simple to connect a host micro controller via the UART interface. The comprehensive function set includes LDOs and step down DC-DC converter, on chip oscillators and a user SPI interface for configuration and read back of fault indicators. The output stage provides overcurrent, reverse polarity and thermal protection and is tolerant to +/- 40V input. It is configurable as push-pull, open drain (PMOS or NMOS) or input only.

Package options include a 4mm x 4mm, 0.5mm pitch QFN with an addition option of a 2mm x 2.6mm, 0.5mm pitch WLCSP. These options make the CC4502 suitable for demanding industrial applications where power dissipation or space are highly important.

The CCE4502 transceiver is suitable for IO-Link Device applications and is compliant with the IO-Link interface and system specification Version 1.1.2 from July 2013 accessible via

For a complete end-to-end system solution, Dialog also provides CCE4510 two channel IO-Link Master Phy. Please click here for more information.
